- Guide to Documentation
  This guide provides information about the Multi-Access Gateway – controller (MAG-c) documentation.
- Overview
  This guide provides an overview of the Nokia control and user plane separation (CUPS) solution. The control plane (CP) is known as the Nokia Multi-Access Gateway – controller (MAG-c) and has the ability to control SR OS based user planes (UPs). The various UP functions include BNG, combined SGW/PGW, and 5G UPF.

  - Introduction to CUPS
    CUPS is an architecture that gains popularity in the mobile core. The architecture was first adopted in the 4G Long Term Evolution (LTE) mobile core and later became the standard architecture for the 5G core. In 2019, BBF began a BNG CUPS project and subsequently standardized the BNG CUPS architecture in TR-459, TR-459.2, and TR-459.3. BBF continues to define new standardized features and solutions contributed by service providers and vendors.
  - Nokia multi-access broadband CUPS solution
    The Nokia cloud-based converged broadband CUPS architecture enhances the triple play service delivery architecture (TPSDA). The Nokia MAG-c implements both the fixed access and fixed wireless access (FWA) CP functions. The Nokia SR OS-based MAG-u implements both the fixed access and FWA UP functions.
  - Nokia value propositions
    A CUPS architecture disaggregates session management between the CP and the UP. The CUPS architecture provides the advantage of independent scaling and independent life cycle management.
